UNITED STATES PATENT OFFICE.

GARLAND E. MILLIKEN, OF DOVER. TENNESSEE.

SUBMARINE TELESCOPE.

Application filed March 17,

To all whom, it may concern:

Be it known that I, GARLAND E. MILLIKEN. a citizen of the United States, residing at Dover, in the county of Stewart and State of Tennessee, have invented certain new and useful Improvements in Submarine Telescopes, of which the following is a specification.

This invention relates to new and useful improvements in submarine telescopes, and has for its principal object to provide a simple and eflicient device, which is adapted for use in locating submerged objects located beneath the surface of the water, means being provided for reflecting a light downward on the objects to be viewed.

A further object of the invention is to provide a device of the above mentioned character, which is of such a construction as to enable a person to view the submerged objects located below the surface of the water, from a point above the surface, means being associated with the upper portion of the device, for permitting a person to illuminate the objects to be viewed.

A further object of the invention is to provide a device of the above mentioned character, wherein the parts are so arranged as to be water tight when a device is submerged.

A further object of the invention is to provide a device of the above mentioned character, which is simple in construction, inexpensive, strong and durable, and further well adapted for the purposes for which it is designated.

Other objects and advantages of this invention will become apparent during the course of the following description:

In the accompanying drawing, forming a part of this specification, and in which like numerals designate like parts throughout the same:

Figure 1 is a side elevation of my improved device with the lower portion thereof shown in section, and

Figure 2 is a transverse section, taken approximately on the line 2-2 of Figure 1.

In the drawing, wherein for the purpose of invention is shown the preferred embodiment of my invention, the numeral 1 designates an elongated tubular member, which tapers gradually toward its upper end. Adapted to be removably supported on the enlarged lower end of the tubular member 1, is the hollow transparent mem- 1924. Serial No. 699,821.

her The upper portion or neck portion 3 of the hollow tubular member 2, is provided with the external threads 4, for cooperation with the internal threads 5, formed on the interior of the tubular member 1, on the lower end thereof, in the manner as clearly shown in Figure 1 of the drawing. 7

The bottom of the tubular member 2 is closed as is shown at 4 in the drawing. Disposed between the outer lower edge of the tubular member 1, and the adjacent portion of the hollow transparent member 2, is the rubber gasket 7, which provides a water proof joint between the transparent member and the tubular member.

Also supported on the lowerend of the tubular member 1. is the reflector 8. The upper portion of the reflector 8 is provided with an internally threaded collar 9, which cooperates with the external threads 10 provided on the tubular body member 1. adjacent the lower end thereof, whereby the reflector may be movably supported thereon. The reflector 8 is substantially bowl shaped, and the lower portion thereof tapers inwardly, as shown at 11 in the drawing, so that the lower edges of the reflector abuts the outer lower edges of the hollow transparent member 2, in a manner as clearly shown in Figure 1 of the drawing.

Adapted to extend through a suitable opening provided in the tubular member 1, and arranged substantially at a point between the externally threaded portion 10, and the internally threaded portion 5. is the electric bulb 12. In this manner, the electric bulb 12 will be disposed between the upper portion of the reflector, and the upper portion of the hollow transparent member 2 in the manner as shown. The wiring 13, for the electric light bulb extends upwardly through the tubular member 1, and one of the wires is connected to a suitable source of electric current, such as a battery or the like, illustrated at 14, the latter being preferably mounted on the outer upper portion of the tubular member 2. and the other wire has its upper end connected to a suitable switch member 15, which is adapted to cooperate with the battery 14, in closing the circuit to illuminate the electric light 12. This construction is within easy access to the person using the device, as will be presently described. The top of the tubular member 1, is open as is shownat 16 in the drawing. and provides a means whereby the person may look into the tube.

An eye 17 is provided on the tubular memher 1, for the purpose ofv permitting the same to be suspended, by any suitable means, such as a chain or the like, not shown, for preventing the loss of the same, and furthermore holding the device in position when in use. If desired, it is to be also understood that more than one electric light may be used in connection with the device, and I do not wish to limit myself to the particular number of lights to be used for carrying out the object of the present invention.

In use, the tubular member 1 has its lower portion submerged below the lower surface of the water, and the glass bottom 6 will provide a means whereby a person looking into the tube from the upper end thereof may locate. and readily view the object below the surface of the water, and which lie on the bottom of the river bed or the like. In order to further view the objects located, the person using the device, at which the switch 15 serves-to close the circuit for the electric light 12, and the reflector 8 will reflect the rays of light therefrom through the transparent member and the bottom thereof, so that the objects may be readily visible to the person viewing the same. Furthermore, the parts which are submerged, are so arranged as to prevent the possibility of any water passing upwardly into the tubular member so as to render the device inoperative. The simplicity, which my submarine telescope is constructed with, enables the same to be manufactured at a very low cost, and will be especially useful to fishermen.

While I have shown the preferred embodiment of my invention, it is to be understood that various changes in the size, shape, and arrangement of parts may be resorted to, without departing from the spirit of the invention, and the scope of the appended claims.

Having thus described my invention, what I claim is:

1. A device of the class described comprising an elongated tubular member, a hollow transparent member having its upper end open, and adapted to be removably supported on the lower end of the tubular member, the bottom of said transparent member being closed, a reflector carried by the lower end of said tubular member and surrounding the transparent member, and illuminating means supported by said tubular member and disposed between the reflector and transparent member.

2. A device of the class described comprising an elongated tubular member, a hollow transparent member open at its upper end, a collar formed on the upper end of said transparent member. and adapted to be removably supported in the lower end of said tubular member, the bottom of said transparent member being closed, a reflector removably supported on the lower end of said tubular member and encircling said transparent member, an electric light supported in the lower end of said tubular member and disposed between said reflector and said transparent member respectively, and means mounted on the upper end of the tubular member for illuminating said electric light.

3. A device of the class described comprising an elongated tubular member tapering gradually toward its upper end, a transparent member having itsuppe-r end open and its bottom closed, a collar provided on the upper end of said transparent member and adapted to be removably supported in the lower end of the tubular member, a reflector open at its upper and lower ends respectively, the upper portion of the reflector having a collar formed thereon and providing means for removably supporting the reflector on the lower end of the tubular member, said reflector adapted to extend around the transparent member in spaced relation thereto, the lower portions of the reflector tapering inwardly for engagement with the outer lower edges of the transparent member, and illuminating means supported by the lower end of the tubular member and disposed between the upper portions of the reflector and transparent member respectively.

In testimony whereof I aflix my signature.

GARLAND E. MILLIKEN.
